"Killer Queen has been in my vocabulary since I was 15. Freddie Mercury painted the lyrics of this woman who I wanted to be. She seemed very powerful, and she captivated a room when she walked in," she said.
"I feel like, after all this time, it was appropriate to use that name in association with something I did. I feel like I'm falling, finally, into that woman Freddie painted," she added.
